Secretomes From Non-Small Cell Lung Cancer Cells Induce Endothelial Plasticity Through a Partial Endothelial-to-Mesenchymal Transition.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimThe tumor microenvironment (TME) of non-small cell lung cancer (NSCLC) is highly heterogeneous and is involved in tumorigenesis and resistance to therapy. Among the cells of the TME, endothelial cells are associated with the latter processes through endothelial-to-mesenchymal transition (EndMT). During EndMT, endothelial cells (ECs) progressively lose their endothelial phenotype in favor of a mesenchymal phenotype, which favors the production of cancer-associated fibroblasts (CAFs). Our study aimed to investigate the consequences of exposure to different lung tumor secretomes on EC phenotype and plasticity. MATERIALS AND
methodsConditioned media (CM) were prepared from the tumor cell lines A549, H1755, H23, H1437, and H1975. Proliferation and migration of ECs treated with these CMs were assessed by Cyquant and Incucyte technologies, respectively. The angiogenic capacity of ECs was assessed by following tubulogenesis on Matrigel. Phenotypic changes in treated ECs were detected by flow cytometry. Morphological analysis of actin fibers was performed by immunohistochemistry, while proteomic analysis by mass spectrometry was used to identify the protein content of secretomes.
resultsA change of the endothelial phenotype was found when human umbilical vein endothelial cells (HUVECs) were treated with different CMs. This phenotypic change was associated with a morphological change, an increase in both stress fiber expression and spontaneous migration. Furthermore, an increase in mesenchymal markers (α-SMA and CD44) confirmed the phenotypic changes. However, the secretomes did not modify the rate of double-labeled cells (vWF
conclusionTaken together, these data suggest that CMs can induce partial EndMT.
